The United Soccer League, which runs the United States Soccer Federation-sanctioned second, third, and fourth-tier leagues, has been hard at work this past year creating a unified system. The recent broadcasting deal to have all USL League One games on ESPN+ is another step in the right direction.
The USL has run multiple leagues for several years now. Originally, it was the third division USL Pro and fourth division Premier Development League. When the United Soccer League made the jump into the second division, it began looking to create a league to fill the now-vacant third division. That league will be starting at the end of March.
